美国的土地管理及其借鉴

在土地管理方面,美国的土地使用管理体系、土地规划制度及规范土地使用的联邦及州法律颇具特色。尽管中国和美国的城市在规范土地的使用方面有不少共同之处,但是,其规定所依据的前提以及规定的具体实施则有很大差异。毋庸置疑,借鉴美国的土地管理经验对于完善我国的土地管理制度、土地规划制度、环境评价制度,合理利用、开发土地,加快城市化进程是大有裨益的。     

Prison population growth and crime reduction

The impact of state prison populations on crime is typically estimated by applying the lambda, the individual crime rate, of prisoners or arrestees. We outline the problems with this approach, attempt to reanalyze the widely divergent lambdas derived in past research, and make adjustments necessary to use lambdas for estimating the incapacitation impact. The result is an uncertain estimate of 16 to 25 index crimes averted per year per each additional prisoner. We argue that regression analysis can provide a better estimate of the impact of prison population growth. Applying the Granger test to pooled state data over 19 years, we found that prison population growth leads to lower crime rates but that crime rate changes have little or no short-term impact on prison population growth. Next we regressed crime rates on prison population and conclude that, on average, at least 17 index crimes are averted per additional prisoner. The impact is limited mainly to property crime.     

Blunt Craniofacial Trauma as a Manifestation of Excited Delirium Caused by New Psychoactive Substances

The body of a 19‐year‐old male was found apparently concealed underneath bushes with recent head and facial trauma, and multiple superficial abrasions. Subsequently, it was discovered that the decedent had been running into objects and buildings following the ingestion the evening before of what was thought to be lysergic acid diethylamide (LSD). Blood staining of a nearby wall close to where the body was lying was in keeping with the described behavior. Toxicology revealed 3,4‐methylenedioxymethamphetamine (Ecstasy), in addition to two only recently available drugs 2‐(4‐bromo‐2,5‐dimethoxyphenyl)‐N‐[(2‐methoxyphenyl)methyl]ethanamine, (25B‐NBOMe), and 1‐(3,4‐methylenedioxyphenyl)‐2‐(1‐pyrrolidinyl)‐1‐butanone, (MDPBP). At autopsy, the skull was fractured with cerebral swelling, contusions, and subarachnoid hemorrhage. Death was due to blunt cranial trauma against a background of mixed drug toxicity. The case demonstrates a rare cause of death in a drug‐induced acute delirium, as well as highlighting two new designer street drugs that may result in significant aberrant behavior.     

Modification of the Marmarou and Foda model of diffuse axonal injury (DAI) improves percentage survival of rats at 24 h and increases the amount of DAI identified

More than two decades ago, Marmarou published a valid model for producing diffuse axonal injury (DAI) in rats. Since then, both mild and severe injuries have been obtained by researchers using the original method and a weight of 450 g. However, the diffuse brain injuries produced in rats were only similar to those seen in humans when the rats sustained severe brain injuries. In these cases, rat mortality in the original article was around 50%, and the cause of death was prolonged apnea post-impact. Rat survival after impact is critical for studying the progression of DAI. In order to explain the cause of death in human victims with cranial trauma who do not show gross brain injury, testing for the presence of DAI is essential. Thus, in order to minimize local and cervical injuries to increase rat survival, attention should be paid to the following aspects: a wider head protector disc should be used, the head of the rat should be elevated at the time of impact, and the foam bed should be soft enough to allow the movement caused by acceleration. With our modified method, rat survival increased by 30% compared to the original model (80% versus 50%). Moreover, 85.7% of rats demonstrated DAI after 24 h of survival. With these modifications, injuries appear in the same locations as in humans; thus, the method is suitable for the study of traumatic DAI in humans.     

Severe Retinal Hemorrhages with Retinoschisis in Infants are Not Pathognomonic for Abusive Head Trauma

The combination of subdural hemorrhage (SDH), retinal hemorrhage (RH), and encephalopathy, or the presence of severe retinal hemorrhages alone in infants, is often attributed to and has been stated to be pathognomonic for abusive head trauma (AHT) or shaken baby syndrome. These beliefs have been challenged, because the same constellation of findings has been identified in accidental head injuries and natural diseases, and most if not all of the studies that support the concept of diagnostic specificity have serious flaws in their methodology. Presented here are two cases of severe retinal hemorrhages with retinoschisis associated with subdural hemorrhage in a natural disease and with severe cerebral edema in an accidental head injury. These cases challenge the dogma that severe retinal hemorrhages with retinoschisis are pathognomonic for AHT.     

Loosening the ties that bind: the hidden harms of civil gang injunctions in San Diego County

Civil gang injunctions (CGIs) are court-ordered restraining orders that are being utilized in the name of controlling the daily routine of alleged gang members, reducing crime, and eliminating ‘public nuisances’ in working-class neighborhoods of color. In this study, we draw upon interviews and court observations conducted between 2009 and 2014 in San Diego County to examine the perceptions of a subset of those who have been listed on CGIs or other gang suppression methods, and those who work closely with them, about their individual and collective impacts. We find that the men and women in our study experience several hidden harms of gang enforcement measures that damage their ability to connect with others in the community, including their own family members and friends; and reduce their ability to pursue opportunities related to education, housing, and employment. We demonstrate that the loss of these bonds to community and opportunities, leads to perceptions of injustice and, in some instances, a transformation in gang activity, rather than its elimination. Ultimately, these exploratory findings raise questions about the logic and justice of gang suppression.     

美国文化价值观对美国外交的影响

自美国踏上国际舞台之日起,其外交就带有一个明显的特点,即价值观化。以天赋使命观、种族优越论、扩张意识、实用主义等为基本特征的美国文化隐形影响、指导、规范着美国对外政策的制定与实施,并在对外政策中得到充分的体现。同时,美国外交赤裸裸地强行输出美式民主、自由等价值观,这种观念和行为深刻影响着国际社会。     

日本智库对中国崛起的研究

日本智库在对华决策方面发挥着重要作用,目前日本智库对于中国崛起的研究较多。多数日本智库看好中国崛起的前景,认为中国崛起在经济上给日本带来了许多机遇,同时也提出了在军事和战略上的各种隐忧。他们认为应加强同中国的交流与合作,抓住中国崛起带来的各种机遇,另一方面也要针对中国崛起可能带来的威胁加强防范。     

Regulating Assisted Reproduction in Canada,Switzerland, and the USA: Comparing the Judicialization of Policy-Making

This article analyses the extent to which courts shape policies for assisted reproduction. While the USA is considered to be the most litigious country, Canada has observed a growing involvement of the courts from the 1980s onward, and Switzerland is characterized by a modest degree of judicialization. Based on national patterns, we would expect litigation and court impact to vary across these three countries. As the empirical analysis reveals, policy-process-specific variables such as the novelty of regulation, self-regulation by key stakeholders, and the policies in place better explain the variation in the judicialization of policy-making.     

Low-Hanging Fruit: Leadership,Perceived Prosocial Impact,and Employee Motivation

Transformational leadership affects public service motivation, but little is known about the context dependency of this association. If citizen contact and, therefore, relative perceived impacts on others and society differ, the association between transformational leadership and motivation is also expected to differ. Analyzing public employees and their leaders from four organizational contexts, we find that employees have relatively higher perceived impact on others and are more user-oriented in contexts with high citizen contact. The association between transformational leadership and employee motivation also depends on employees’ perceived impact, implying that some fruit hangs lower than other when leaders try to increase employee motivation.
